Question
Write three short responses of approximately 125 words each (approximately 375 words total) that answer each of the following questions: What are the major factors that contribute to environmental problems on a global scale? Why are these factors unsustainable? What is the difference between a scientific law and a scientific theory? How do scientists arrive at these conclusions, and what are the limitations of scientific research? Where do humans get the energy that they use to maintain their existence, such as eating, working, and having a family? In your answer, address the difference between renewable and nonrenewable resources.
Explanation / Answer
Major factors causing Environmental unrest are
-A scientific Law is a statement based on experimental observations that describes some aspects of the universe while a scientific Theory explains that law like it tells why such a thing is there or the causes related to it.
Limitations include -
-Humans have survived on earth from very long .Their basic needs includes food , shelter and cloth for survival and our ancestors have survived with these. So if it is about the energy which allows us to do work basically comes in a process chain that we do in our life. We in our current era ,the humans are more advanced than any other period and we grow in a civilized manner.We do several things .We perform several duties , have a family etc as they are all a life process done for sustainability.
-Renewable Source of energy include Solar provided by sunlight , Wind , Biomass , Geothermal energy etc.
They are limitless and non - exhaustable so we should be considering to use this type more but the only reason it is not being implied is because they are little expensive in thier application but we have to use it anyway since our non renewable source will be exhausted after some time.
Non - renewable source of energy includes coal , natural gas , oils (Fossil Fuels).These are limited in nature and are also available in less places . It is cheap at some point and but after it gets exhausted it is very hard to get and also very expensive . It causes pollution of different types and ultimately harms our environment. Because it is very efficient and we have got used to this source for energy we prefer using coal for our electric production which is later used in life forms etc.
